Steelers quarterback Ben Roethlisberger practiced Saturday but remains questionable for Monday night's game at San Francisco.

Roethlisberger sprained his left ankle during a 14-3 win over Cleveland on Dec. 8. He did not speak to reporters following practice, but guard Ramon Foster said the quarterback showed little problems throwing the ball despite limited mobility.

"I could see him playing against the 49ers," Foster said. "I guess we won't know for sure for a couple days, but with a late Monday night game and two more days to rest and rehab I think he'll be all right to play. And I certainly wouldn't bet against him."
